Is there a way to include multiple cylinders in the template data, or to copy the cylinder set up from one dive to another (without copying the entire dive).

On a deep dive on my CCR I can have up to 5 cylinders, 2 on my re-breather and 3 bailout. As the bailouts are only used in an emergency they tend to have standard gasses in them, so would copy across really easily.

Yes, this is something on top of my todo list. But it's actually not so easy, because usually the cylinders are already created partly from downloading the dive computer. So it is normally not about copying the cylinders, it's about copying and merging the data like tank size and tank type. But matching which data goes into which cylinder is not trivial.

Such a function has to deal with all kind of combinations, like copying 5 cylinders into a dive with 3 cylinders or just one. I'm not sure how to do this properly.
